Changelog

Fixed

Security: Image Studio now encodes the media ID in its requests, as extra hardening.
Trashing a post now deletes its vectors through each environment's own vector DB.
On mobile, the Glass and Timeless chatbots keep the input above the keyboard in long conversations.
A page that places the site-wide chatbot as a popup no longer shows it twice.

Added

MCP Undo: every change an assistant makes can be undone in one click from the MCP tab, or just by asking, and the undo stops if someone edited the item since.
MCP approvals: approve deletions (or every site change) from the MCP tab, or keep assistants on drafts only.
MCP edits Gutenberg posts block by block, and turns Markdown into real blocks.
MCP works with your SEO plugin (Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework, Slim SEO, SEO Engine) and with Advanced Custom Fields.
MCP edits pages built with Elementor and Beaver Builder (Pro), Divi, Avada, WPBakery and SiteOrigin.
MCP manages menus, CSS, site styles, block theme templates, classic widgets, WooCommerce coupons and variations, comments, draft previews and Redirection redirects, and reads form entries.
MCP checks pages as visitors see them, reads the error log and Site Health, and restores revisions.
Assistants get a short introduction to the site and starter prompts when they connect.
Auto Sync can target several embeddings environments, with the mwai_embeddings_sync_env_ids filter.
The chatbot launcher can reuse the AI avatar.

Improved

Redesigned MCP tab: the token setup lives in Connect, integrations show as chips, activity covers 30 days, and the Claude and ChatGPT directory links go through Meow Apps' connector.
MCP tools that can break things are flagged so assistants ask before running them, and tool descriptions are shorter.
Turning on Cross-Site for a chatbot also turns on Popup.
